Specification of Letters Patent.

Patented June 5, 196.

Application filed July 12,1905. Serial No. 269,336.

To all whom zit muy conceive:

Be it known that I, CHARLES VIEBKE, a citizen of the United States, residing in the borough of the Bronx, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Chenille-Machines, of which the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.

My invention relates to chenille-machines, and has for its objects the production of the chenille by continuous operation of the machine and in endless form and at an increased rate of production. f

It also has for its objects simplicity and compactness of the construction of the machine, ready adjustability of parts, ease and reliability of operation, and the realization of other advantageous features which will appear from the following description of a machine embodying my invention.

My invention includes the provision of two parts rotating in the same direction, each part carrying thread or wire or other suitable material for performing the work of holding the loops of silk or yarn or other suitable ornamental or surface material.

In the following specification and claims the body or holding or binding material will be designated as binder-threads and the ornamental or surface material will be design nated as surface threads.

My invention also includes a loop-former or pin, upon wlL'ch the loops of surface thread are formed, and means for supplying the surface thread thereto.

My invention also includes various other parts, as will appear from the following description.

I will now describe the constructions embodying my invention illustrated in the accompanying drawings and will thereafter point out my invention in claims.

Fig. 3 is a side elevation, partly in central section, of the upper part of the machine. Fig. 4 is a detached elevation of the upper part of the surface-thread bobbin-carrying post with the bobbins thereon. Fig. 5 is an enlarged cross-section of the completed set-off chenille. Fig. 6 is a longitudinal view of the same. Fig. 7 is a side elevation of the upper part of the machine as fitted for making ordinary chenille. Fig. 8 is a horizontal central section looking upward of the rear portion of the front or secondary binder-thread arbor and the secondary binder-thread bobbin-holder and bobbin carried thereby fitted for ordi= nary chenille, as shown in Fig. 7. Fig. rQis a rear end elevation of the same. Fig. 10 is an enlarged cross-section of ordinary chenille, showing the binderethreads and surface threads, the loo s of the latter having been cut to produce t 's style of chenille. is a side elevation of the upper part of the machine fitted for making cut and uncut chenille. Fig. 12 is a rear end elevation of thefront or secondary binder-thread arbor, showing the secondary binder-thread bobbins and knife fitted for cut and uncut che- Fig. 11.

nille, as shown in Fig. 11. Fig. 13 is a den tached elevation of the upper part of the sur face-thread bobbin-carrying post and pins. Fig. 14 is an enlarged cross-section of the completed cut and uncut chenille, showing the binder-threads and surface threads, one of the two loops of the latter having been cut to produce this style of chenille.

Extending across the top of the frame 1 and mountedthereon are two bearing-supporting rails 2 and 3, upon which yare secured a plurality of bearings 4 and 5, within which rotate a series of hollow arbors 6 and 7, consisting of hollow tubes, over the rear ends of which are fitted and secured binder-thread bobbin-carrying heads 8 and 9.

The machine shown is constructed to simultaneously produce in parallel four lengths of chenille, and the chenille-producing parts are therefore quadrupled in parallel arrangement on the one frame. A single chenilleproducing mechanism will now be described, comprising a rear hollow arbor 7 and its pri mary binder-thread bobbin-carrying head 9, and a front hollow arbor 6 and its secondary binder-thread bobbin-carrying head 8, and other parts to be hereinafter described.

The head 9 on the rear arbor carries the bobbin 10, from which the primary binderthiead a is fed to the machine. The construction of the bobbinholder 11 will be hereinafter described, it being here noted that it extends obliquely from the rear face of the head 9.

Within the rear hollow arbor 7 is fitted to slide longitudinally the loop-former operating-tube 12, which has at its front end the loop former 13. This loop -former 13 is shown as driven into the front end of its tube IOO IOS

412 and the usual tapering form aridigrooved for the passage of the primary` of set-0H chenille, this loop-former is recipro-Y cated intervals from the forward position shownin Figs, 1 and 2 to the rearward ositionshown in Fig. 3. When in forwar pos ition, Ait presents an unbroken surface in common with 4thefcollan1 4 on the front' end of the rear .arbor 7 .tdreceive' the surface thread or silk c, which is wound thereon from stationary guideandtnsion devices and fed the.

tate on tationary axes.l

" Upv thev loop-form slot-118 of `greaterlength than its reciprocating or longitudinal movement is provided,

into which fits the projecting end of a setscrew 17, which secures the head 9 to the arbor 7, and this projecting end of the setscrew guides the tube 12, assuring a rotary movement thereof in common with the arbor and permitting the reciprocating movement fjthisftubeJrelativelyto the arbor.- Dia-.

me ricallyo positelthis slot 18 a second slotfv 19 lis ,t oughwhicli the primary binderthread a4 passes' from its bobbin into the tube 12.

The front hollow, arbor 6 is rotated in the same direction and at the same speed as the rear hollow arbor 7 above described and resembles the rearhollowarborin construction, having at tsrear end thebobbin-carrying head 8,- above referred to, and this head having thebobbin-carrier 21,- carrying the bobbin 20for .thesecondary binder-thread A guide-roller 22-is also-provided-7 thefunction offwhich isto deliventhesecondary binder-j` threadib in desired position to grip the loops of the vsurface thread c against the primaryv binde if-thread gil/ as loops are delivered f'ro 'L theloop-former 13. This guide-roller 22 is carried'by a pivotally-mounted bracket l 23, shown as pivoted upon the U-shaped bobbin-carrying bracket 21 and controlled by adjusting-screws 24 25,- which are usually adjustedtopermit of slight play between them;. In the construction shown in Figs. 1, 2, and

3,5with the machine fitted to produce set-olf chenille, a single primary binder-thread and a- 'single secondary binder-.thread are employed, and therefore each rotating arbor carries a single bobbin, anda counterw'eight 2'6 is provided on each head diametrically opposite the bobbin to ro tatively balance the parts.

In the construction shown in Figs. 7, 8, and 9- and particularly claimed herein, in which Athe machine is fitted to produce ordinary chenille, a single primary binder-thread bobbin 10 yand its carrier 11 are provided and also1a" counterbalance 26 but the secondary binder-thread'bobbi-nand,its carrier 21 are combinedfwi-th a knife orloop-cutter 27, carried on the same head and which, with its suppo'rting-post 28, rotatively counterbalances the bobbin, guide-roller, and carriers. The details of the common construction of all of Ythe bobbin-carriers are well illustrated in Figs. 8 and 9 in connection wi th `this arrangement of parts and will now be particularly described.

At one sideof the U-shaped bracket a retaining-spring 29 is arranged to press against the outer face of the bracket and is perforated to `receive the end of the bobbin-spindle 30,V and.this bobbinspindleis pivoted in the lother arm of the bracket,'and both arms of @the bracket are suitably slotted to permit the erf tubeV 12 a' narrow;i

f bobbinspindle to be freely swung on its pivot 'to present one 'end for vthe insertion or removable of the bobbin.' Inj swinging the spindle to the `fbobbiri- 1`-ctain'ing positionV shown tho outer end of the.pin, "shown"as o'b-l liquely rounded, engages and pushes outf ward thc retaining-spring 30 until the perfo-'j `rati on of the' spring registers with theend of the spindle, and thereupon the spring will I.move inward over the spindle to the locked lposition shown. To unlock the spindle, it is only necessary to press the retaining-spring outward clear of the end of the spindle. The `bobbin-holder also has a tension-spring 31 vlocated between the bobbin-head and the inner face of the arm of the bracket opposite to the arm carryingthe retaining-spring 29. The surface-thread'bobbins 15 16 are carried on stationary spindles 32,which project `from collars 33, suitably clamped upon the `post 34, as by set-screws,'a s shown Suit- ,able tensionand guiding devices 3 5are also icarried on collarsclarnped upon this post 34. It :will benoted that one post jcarriesthe l'bobbins j and tension and ,guide devices for t'wo adjacent `parallel chenille-producing mechanisms, as shown in Figs, 2 'and 4, althrough for clearness of illustration this duplicationof parts on the same post isomitted .from the other .portions of the drawings.-

eXtreme front of themachine and comprises .an upper drawing-roller 37 and a lower drawing-roller 3S for each chenille-producing lmechanism, these rollers being geared ,to-- gether by gears 39 40, having deep teeth, and the upper drawing-rollers 37 being carried by andffitted to rotate on studs projecting from arms 42, these arms 42 being loosely pivot-l ally mounted between fixed collars on a sta-v tionary shaft 41, extending acrossthe frame, yThe upperand lower drawing-rollers are in the `shape o f complementary frustuins of cones, the lower drawingrollers havingv rims to prevent the chenille from running offlaterally therefrom. Each' lowerv drawing-roller is fixed upon a .rotating .shaft 84, extending across the frame at .the eXtreme frontend thereofl'and mounted `-bearings thereon.kv

yThe drawing mechanism is located atthe i The tension is maintained by the weights of the upper drawing-rollers and attached parts, and each upper roller may be separately lifted clear of its lower roller whenever such movement is desirable or necessary. The completed chenille drawn out by these rollers may be deposited in any suitable receptacle or wound on reels.

The mechanism shown for actuating the various parts will now be described. The driving-shaft 36 is at the front of the machine and is fitted in bearings secured to the front standards of the frame. A sprocketwheel 43, centrallyxed upon the drivingshaft, imparts rotary motion by means of a chain 44 to a sprocket-pinion 45, fixed upon a longitudinally-arranged intermediate shaft 46, suitable idler-sprockets 47 being provided near the bottom of the frame to guide the chain and allow considerable vertical length of the chain in which the chain may freely turn through the right angle required by the right-angular relation of the two shafts.

The longitudinal intermediate shaft 46 is provided with spur-gears 48 49, which respectively mesh with intermediate spur-gears 50. and 51, located vertically over the longitudinal intermediate shaft 46, and the intermediate gear 50 is one of a train of gears including a gear 52 on each secondary binder-thread arbor 6 and including other intermediate gears 53 between these arbor-gears, and the intermediate gear 51 is one of a train of gears including a gear 54 on each primary binderthread arbor 7 and including other intermediate gears 55 between these last-mentioned arbor-gears, and by this gearing all of the arbors are rotated in the same direction and at the same high rate of speed.

A sprocket-pinion 56 is fixed upon the driving-shaft 36, near the left end thereof, and imparts rotary motion by means of a chain 57 to a large sprocket-wheel 58, fixed upon another intermediate shaft 59, extending across the frame and fitted to rotate in bearings thereon. F rom this slow-speed intermediate shaft 59 motion is transmitted to the loop-former reciprocating mechanism and to the drawing mechanism.

For the operation of the loop-former reciprocating mechanism a cam-shaft 60 is provided litted to rotate in bearings near the rear end of the frame and is connected with the slow-speed intermediate shaft 59 by reversely-arranged stepped cone-pulleys 62 and 61 on the respective shafts and a drivingcord 63 and a tension-pulley 64, loosely mounted on a pin 66, carried by a weighted pivotally-mounted arm 65, engaging with the lower length of the driving-cord. This construction permits a large range of variation of the speed of the cam-shaft 60 by shifting the driving-cord 63 upon the stepped conepulleys 61 and 62.

A cam 67 is -fixed upon the cam-shaft 60 and works against a cam-roller 68, rotatively mounted upon an arm 69. This arm 69 is secured at its lower end upon a rock-shaft 70, extending across the frame and mounted in bearings thereon. A helical extension-spring 85 yieldingly holds the arm 69 forward, so that the cam-roller 68 will be pressed against the cam 67. The arm 69 is duplicated by another arm 71, fixed upon the rock-shaft 70 at the other end thereof, and at the upper end of each arm 69 71 a connecting-rod 72 connects each arm with a cross-bar 73, which engages each loop-former tube 12 of the four parallel chenille-forming mechanisms shown, resting between collars thereon, so as to permit free rotative movement thereof while simultaneously imparting to all of these tubes the reciprocating movement longitudinally of the machine imparted to the cross-bar 73 by the cam 67.

The drawingmechanism receives rotary motion from the slow intermediate shaft 59 through another intermediate shaft 74, these two shafts being connected by reversely-arranged stepped cone-pulleys 75 and 76 on the respective shafts and a driving-cord 77 and idler-pulleys 78, loosely mounted on a pin 79, carried by a weighted pivotally-mounted arm 80. The shaft 74 has a sprocket-pinion 81 at its right end outside the frame, connected by a chain 82 with a sprocket-wheel 83 on the shaftv 84, which carries the lower drawing-rollers 38, as above described. This construction permits of a large range of variation of the speed of the drawing-rollers by shifting the driving-cord 77 on the stepped cone-pulleys 75 and 76.

In the operation of the machine when fitted for the production of set-0H chenille, as shown in Figs. 1, 2, and 3, loops of normal length will be produced by the winding of the surface threads c about the loop-former 13 when the loop-former is in forward position. The primary binder-thread a will be within these loops, and the secondarybinderthread b will be applied exteriorly to these loops. The twist of the binder-threads and loops will be imparted by the rotative movement of the two binder-thread-carrying parts or arbors relatively to the drawing mechanism. The withdrawal of the loopformer will result in the twisting of all of the threads together without looping. This position of parts is shown in Fig. 3, and the resulting set-off chenille is shown in Figs. 5 and 6. The spacing of the looped and unlooped portions may be varied by varying the speed of the cam 67 in the manner above explained.

Should it be desired to 'produce ordinary rough or uncut chenille, it is onlynecessary to throw off the driving-cord 63 and move the cam so that the loop-former 13 will be in the forward position. (Shown in Figs. 1 and 2.)

For the production of ordinary or cut chelOO IIO

nille the counterweight 26 on the forward or secondary binder-thread-carrying head 8 will be replaced by a knife-post 28 and a knife or loop-cutter 27, carried thereby, (see Figs. 7 and 9,) and a suitably-shapedv loopformer 86, preferably thin and of rectangular cross-section, as shown, and slightly grooved to receive the edge of the knife will be substituted for the rounded loop-former 13 and the loop-former reciprocating parts disconnected or omitted. The ordinary cut chenille which will then be produced is shown in Fig. 10. This fitting of parts of the machine produces the construction which is particularly claimed herein..

For the production of cut and uncut chenille a duplication of primary binder-thread bobbin 10 and of the secondary binderthread bobbin 20 will be required, and a knife or loop-cutter will also be required. The required arrangement of parts is shown in Figs. 11 and 12. The knife 27 is here arranged parallel to the axes of the bobbins, and the loop-former correspondingly arranged, and the knife and post are rotatively counterbalanced by a small weight 87. The cut and uncut chenille produced with this arrangement of parts is shown in Fig 14.

Other variations may be made, if desired. In all varieties the chenille maybe produced continuously and of any desired length or practically endless, and the production will be rapid and uniform.

It is obvious that various modifications maybe made in the construction shown and above particularly described within the principle and scope of my invention.
